i just setup Librenms with 1 minute polling.
i am monitoring 10 devices now…
i did setup based on the recommendation from Performance - LibreNMS Docs except dns…
for one of the ex4200 switch stack (2 switch stach ) which is located at 250ms away, it is taking almost 3 minutes to get the polling completed… Any way to increase the performance…
below is my config.php config… is it expected behaviour?
$config['snmp']['max_repeaters'] = 50; #We need reduce it if there is any timeout from the device
$config['snmp']['max_oid'] = 20;
$config['polling']['selected_ports'] = true;

#fping is used to check the connectivity to the device
$config['fping_options']['timeout'] = 300;
$config['fping_options']['count'] = 1; #default is 3 packets
$config['fping_options']['interval'] = 300;
